Which track

[Detective]

Which property of a TMediaPlayer indicates
which track of the CD is playing?

Look at Position to figure out where you are on the disc. (But see also TimeFormat for gotchas with this.) Then roll through the TrackPosition array, from 0 to Tracks-1 (I think), looking for the track with the highest TrackPosition that is less than the current Position. That's the track you're in.

If you want to keep your code simple, you can assume that values in the TrackPosition array are in increasing order; but I don't know if that's always true. Or:

for i := 0 to Tracks - 1 do
    if (Position > TrackPosition[i]) and (Position < TrackPosition[i] + TrackLength[i]) then
        ShowMessage('We''re in track ' + IntToStr(i));
